REINFORCED CONCRETE OR CEMENTITIOUS RAILWAY-TIE.

Specification of Letters Patent.

Patented Feb. 4, 1913.

Application filed August 20, 1912. Serial No. 715,999.

To all whom it may concern Be it known that I, SAMUEL LAW KYLE, asubject of the King of Great Britain, residing at Ottawa, in theProvince of Ontario, Dominion of Canada, have invented certain new anduseful Improvements in Reinforced Concrete or cementitious Railway-Ties,of which the following is the specification.

My invention relates to improvements in reinforced concrete orcementitious railway ties, and the objects of the invention are toprovide a simple and effective form of tie which may be manufacturedwith simple apparatus and at low cost, and at the place where requiredto be used whereby freight charges on the ties may be eliminated and thecost of production reduced.

Further objects are to dispose of the reinforcing material to a maximumof advantage and to lock the same in position within the tie.

Further objects still are to enable the rails to be readily attached tothe tie by the usual means by spikes, avoiding the necessity of applyingany bolts, screws or other complicated form of locking means, and itconsists essentially of the improved construction hereinafter more fullyset forth and described in the accompanying specification and drawings.

In the drawings, Figure 1 is a perspective view of a portion of-thetrack construction embodying the present invention. Fig. 2 is aperspective view of the reinforcing material. Fig. 3 is a crosssectional detail from the rail.

Referring to the drawing, A represents the tie proper which is moldedfrom concrete or other cementitious material in a suitable mold of usualshape.

Following the present invention each tie contains a reinforcing member Bwhich extends from end to end of the same. This member is formed of thinsheet metal such as sheet steel and is provided with reversedcorrugations as shown. Each corrugation comprises vertical side walls 10and 11 and a horizontal wall 12, the side walls being at substantiallyright angle to the horizontal wall whereby all the horizontal walls willlie in parallel planes which will be parallel to the upper and lowersurface of the tie and all the side walls will lie in parallel planeswhich will be parallel to the sides of the tie.

The corrugations are also formed with perforations 13 through which theconcrete may flow to securely lock the reinforcing material on the tie.

C represents bearing members of wood or other suitable material whichare placed on top of the tie to receive the rails D, but convenientyheld in position by means of square headed bolts 14 which extend throughsuitable perforations 15 molded in the tie. The bearing members are ofsuch suflicient thickness as to enable the rails to be spiked through inthe usual way.

In practice the tie proper will be practically embedded in the ballastof the track construction leaving the bearing members C projecting aboutthe same to support the rail thus guarding against an end and sidemovement.

As many changes could be made in the above construction and manyapparently widely different embodiments of my invention, within thescope of the claims, constructed without departing from the spirit orscope thereof, it is intended that all mat ter contained in theaccompanying specification and drawings, shall be interpreted asillustrative and not in a limiting sense.

What I claim as my invention is:

1. A reinforcing cementitious tie having a reinforcing member formedwith reversed corrugations extending from end to end of the tie and fromside to side thereof and bearing members of wood on top of the tie, uponwhich the rails rest, and fastening means for said bearing membersextending through the tie and bearing members.

2. A reinforcing cementitious tie having a reinforcing member formedfrom a plurailty of reversed corrugations extending from end to end ofthe tie, each of said corrugations comprising vertical side wallsparallel with the sides of the tie and a horizontal wall parallel withthe top and bottom of the tie, bearing members on the tie and fasteningmeans for said bearing members extending through the tie.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.

SAMUEL LAW KYLE.
